PRESSER-BAR CONTROL FOR FOUNTAIN-PENS.

Specification of Letters Patent.

Patented May 14, 1918.

7 Application filed January 3, 1916. Serial No. 70,025.

To all whom it may concern:

Be it known that I, FRANK H. MOONEY, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Presser-Bar Control for Fountam-Pens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to fountain pens of the class in which the ink reservoir comprises a compressible tube or bag, the expansion of which, from compressed form, is intended to draw in a supply of ink with which the inlet end of the tube may have communication.

The object of my invention is the provision, in a fountain pen of the character described, of simple and improved means for compressing the ink reservoir during the ink filling operation.

A further object of my invention is the provision of improved means within the pen barrel for anchoring the presser-bar against longitudinal movements.

The invention is fully described in the following specification, and while in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a side view of a fountain pen embodying the invention. Fig. 2 is a sectional view on the line 2-2 in Fig. l with the presser-bar control means in normal position. Fig. 3 is a similar view of a portion of the pen with the presser-bar and its control means in depressed position. Fig. l is a perspective view of a portion of the pen barrel and presser-bar control means in assembling relation, and F ig. 5 is a view illustrating one manner of holding the pen for filling, and Fig. 6 is a detail view of the presser bar.

Referring to the drawings, 1 designates the customary barrel or casing of a fountainpen, 2 the pen point holding member,

and 3 the ink reservoir, which is carried by the member 2, and is of a resilient compressible nature, such, for instance, as a rubber bag of tubular form. Disposed within the barrel 1 at one side of the ink bag 2, and in contact therewith, is a presser-bar 4:, which extends lengthwise of the bag and is adapted to be moved transversely of the barrel to efi'ect a compressing of the bag for a greater portion of its length to eject air therefrom, whereby an expansion of the bag will draw a supply of ink therein, as is well understood in the art.

Fitting closely within the barrel beyond the closed end of the bag 2 is a split ring 5, preferably of spring metal, to adapt it to spring outward against and frictionally engage the wall or shell portion of the barrel. This ring has one end provided with a reentrant extension 6, forming a tongue which extends diametrically of the ring from one side to or near the other thereof and loosely through an opening 7 in one end of the presser-bar, whereby the bar is permitted to have free movements transversely of the barrel and is anchored against movements lengthwise thereof. The spring nature of the ring enables it to be easily inserted in position in the barrel through the open end thereof.

The control means for the presser-bar in the form illustrated comprises a guide 8 and a plunger member 9, both of arcuate or segmental form. The guide 8, which is preferably of metallic bar form of a bendable nature, is provided -at each end, in the present instance, with a tongue 10, which is narrowed with respect to the body of the guide-bar to provide shoulders and is in serted through an opening provided therefor in the barrel side adjacent to the flat side of the presser-bar 4 which is opposed to the ink bag, the tongue then being clenched at its free end against the inner side of the barrel, as shown in Figs. 2 and 3, to retain the guide in engagement therewith. The tongues 10, in the present instance, are inserted through the opposite ends of a slot 11 provided lengthwise in the barrel 1, and the tongue ends are bent outward under the end walls of the slot by inserting a bar or mandrel into the barrel, or in any other suitable or convenient manner,

The plunger 9 is preferably fitted against the inner side of. the guide-bar 8 in concentric relation thereto and has one end provided with aguide loop or part 12, which loosely embraces the guide-bar for sliding movements thereon. The other end of the plunger projects through or registers with a broadened guide portion 13 of the slot 11, at one end thereof, so that the plunger has rotary reciprocatory movements through said guide opening 13 when moved in one direction or the other with respect to the guide-bar 8. The plunger is preferably of such length that when at the limit of its retracting stroke, as shown in Figs. 1, 2 and a, the free end thereof is adjacent to the inner edge of the guide opening 13 in position to coact with and effect a depression of the presserbar 4 within the barrel when the plunger is moved inward, as shown in Fig. 3.

It is evident that the arcuate form of the plunger and its guide causes its inner or presser-bar coacting end to have movement transversely of the barrel to efi'ect a depression or release of the presser-bar when the guide end of the plunger is moved lengthwise with the guide-bar 8. It is also evident that the guide loop or part 12 on the plunger serves as a fingenpiece to facilitate a movement of the plunger. 1% designates a slightly raised portion on the guide-bar 8 for coacting with the plunger guide part 12 when in retracted position to yieldingly retain it in such position. It is found in practice, however, that the provision of means on the guide-bar for resisting an initial movement of the plunger from retracted position is not necessary, as the resiliency of the rubber bag 3 is not only sulficient to lift the presser-bar at and return the plunger to its retracted position when released, but efiectually retains the plunger in such position.

It is preferable to so dispose the plunger that when in retracted position the guide part 12 thereof stands at the end of the guide bar 8 which is adjacent to the pen point, thereby facilitating the filling operation by enabling the user when holding the pen in writing position to engage the guide part 12 with the first finger of the hand holding the pen and easily move the plunger 9 to depress the presser-bar preparatory to filling, as illustrated in Fig. 5.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications without departing from the spirit of the invention as defined by the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,-
